Are U.S. aircraft carriers ice breakers and could they operate in Arctic waters with ease? -...

Maybe someone can come up with a better tag for this story. I couldn't find an obvious fit. So I decided to look at it by asking the question this way: "Is it good tactics to attack an ice floe with an aircraft carrier?" Still, I wanted to share this link because it is an interesting question. It reminded me of a documentary I saw about a new design in ships operating in Arctic waters which allowed them to back into the ice and used their propellers to grind their way through pack ice and floes. Maybe that would be a consideration for warships.
